No.11/806,711 (“Multiple LEDs Light with adjustable angle function”).

Of the above, U.S. patent application Ser. Nos. 11/527,631; 11/498,881;11/255,981; 11/094,215; 12/318,470; 12/318,471; and 12/318,473 alldisclose an “AC power sealed-unit” and “DC powered battery-pack” thatare interchangeable with each other to fit into a “uniform compartment”on the LED light housing. The current invention also involves aninterchangeable sealed AC unit and a DC battery pack, for all kinds ofapplications that may include an LED, such as a toy, gift, game,lighting, camping light, car, miniature cars, sound device, videodevice, music device, or touch device. However, the current inventiondiffers from the inventions of the seven applications that also disclosesealed units in the following respects:

(1) Light Source:

-   -   The earlier filings are limited to an LED as light source. The        current invention covers all low power consumption light        elements, including electro-luminescent elements as well as        LEDs, as the light source.        (2) Light Source within Current Light Device for Common Use:    -   The current light source may be common to both the sealed-unit        and battery-pack so that there is no need for the sealed-unit        and battery-pack to each have its own light source. The earlier        applications of the inventor each disclose a sealed-unit and        battery-pack having its own LED within its own housing.        (3) Light Source Definition:    -   The light sources of the current invention can all be turned on        by DC electric signals supplied by only three relatively low        voltage fresh batteries (such as three Duracell™ alkaline AA        batteries) to provide a light performance that last more than        one hour.

In addition, the sealed unit or battery pack of the current inventionoffers the further improvement that it has its own trigger means, whichmay include any of a push switch, slide switch, conductive switch,sensor, motion sensor, vibration switch, tilt switch, heat switch,moisture switch or any mechanic or electric switch available from theconvention market and that can be selected to use for a DC poweredbattery light device.

The current invention has wide application for any DC powered batteryitems capable of providing a “compartment with uniform connect-means,”because is easy to design the “AC powered sealed-unit” and “DC powerbattery-pack” with the above discussed trigger means to fit each of theexisting battery powered application listed above so that any suchbattery powered application can be converted to an AC powered lightingdevice by replacing the battery pack with an “AC powered sealed-unit”that can be plugged into wall outlet. This will let people buy onebattery-powered application and yet make use of two different powersources for different location requirements. For example, one could buya bathroom floating LED battery operated toy light that can be changedinto an AC powered LED night light to plug into a wall outlet and becomea very cute and eye-catching device. If people think such a device istoo toy like, fine—one could instead change the kids' battery poweredLED flash light to an AC powered flashing light to plug into a wall fornight time illumination, which is more similar to a conventional marketnight light.

The current invention can also, conversely, change a safety AC poweredlight device into a DC powered battery light device by simply swappingthe AC powered sealed-unit for a DC powered battery-pack. This willenable all conventional nice looking AC power night lights to becomebattery powered night lights. Furthermore, it will be noted that thechange to DC powered light devices enabled by the invention can beapplied to all conventional low power consumption AC light devicesbecause all such light sources use direct current to drive them and soone can use the interchangeable features of the invention for all lightdevices of all kinds of categories as long as they are low powerconsumption light devices as described above.

The invention thus provides an interchangeable power source for anylower power consumption light device, enabling the light device toutilize both an AC power source and a battery-operated power source.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The current invention provides a light device with interchangeable powersources, which means that the light device may be powered by an ACpowered sealed-unit or a DC battery-pack that fit into the light deviceand that can be replaced at any time. The light device may includes allkinds of low power consumption light sources, including but not limitedto an LED, electro-luminescent (EL) element, organic EL, organic LED, orany other light source that can be turned on by three Duracell orsimilar alkaline batteries for up to one hour.

Furthermore, the light source utilized by the preferred embodiments canbe arranged within the sealed-unit or battery-pack or the light sourcecan be arranged within the light device and become a common light sourceto be used with either the sealed-unit or battery-pack, so that there isno light source on the sealed-unit and battery-pack. The light sourcefor common use or individual light source within the sealed-unit orbattery unit both fall within the current invention. The light source isnot an expensive part so either arrangement is not a big issue.

FIGS. 15A to 15C show a preferred light device including ahousing-member (S1) with compartment-means (S2′) that can receive an ACpowered sealed-unit (S2″) to cause a light source (S3) (S4) to beilluminated and seen by a viewer. The AC powered sealed-unit (S2″) has apower-source (S7) (S7′), circuit means (S8), and light source (S3) (S4)within the sealed-unit (S2″). The sealed-unit (S2″) also hasassembly-means (S9) (S9′) to make sure that assembly of the sealed-unitto the housing-member (S2″) is very solid.

As shown in FIGS. 15A to 15C, the AC powered sealed-unit (S2″) can bereplaced by DC powered battery-packs (S51) (S52) which have lightsources (S53) (S53′), power sources (S59) (S59′), circuit means (S56)(S56′), trigger means (S57) (S57′), and assembly-means (S55) (S55′)within the battery-packs (S51) (S52) so that both battery-packs canreplace the AC powered sealed-unit because the battery-packs s have thesame size as the sealed unit to fit into the compartment-means (S2′).

In the embodiment of FIGS. 15A to 15C, the first light device (S) can beany kind of low power consumption light source light device. It canprovide front illumination, side illumination or any combination front,back, right, left, upper, and/or bottom side illumination to meet marketrequirements.

As shown in FIGS. 15A to 15C, the sealed-unit (S2″) may also haveconnector-means with wire (S5) to connect with the remote light source.This is optional because some applications need such a sealed-unit (S71)with conductive-means (S72) to connect the AC outlet power sourcethrough the prong-means (S73) to the sealed-unit (S71). The same is trueof the DC power-pack (S61), which may have conductive-means (S62) toprovide electric signal delivery from outside power terminals forconnection to an outside big battery-case (S63), charger, generator,solar module, wind power generator. The plug-means (S65) with conductivemeans can be plugged into a plug-receiving hole (S64) to easily make aconnection.

As also shown in FIGS. 15A to 15C, light device (S10) hascompartment-means (S12′) to receive the sealed-unit (S12) or sealed-unit(S2″). The battery-pack (S31) (S32) can be replaced by the AC poweredsealed-unit (S12) at any time according to the above discussion and thesealed-unit or battery-pack assembled to the housing-member (S10) by anyconventionally available assembly-means (not shown).

FIGS. 15A to 15C also show a light device (S20) that hascompartment-means (S22′) to receive the sealed-unit (S22) or sealed-unit(S2″). The battery pack (S41) can replace the AC power sealed-unit (S22)at any time by screwing the screw-means (S23) (S24) into holes (S23′)(S24′) in the housing-member (S20) or by screwing the screw means (S44)(S44′) (S44″) into holes (S42) (S42′) (S42″) in the housing-member(S20).

According to FIGS. 15A to 15C, the AC powered sealed-unit (S2″) (S71)(S12) has a quick connector (S5) or remote light source (S76) (S12′)connected with the sealed-unit. This kind of electric arrangement isdesigned for a light source away from the sealed-unit body. At thisdate, an appropriate test laboratory such as Underwritters LaboratoriesInc. (hereafter as UL) requires all remote low-voltage DC light sourcesand low voltage related conductive-means to be inside an anti-flammableenclosure (housing). However, the current inventor does not agree withthis UL LED night regulation and believes UL will revise thisunreasonable standard and allow the low voltage light source(s) and lowvoltage electric component(s) to be remote from the sealed-unit withoutany housing or enclosure to surround these parts. This aspect of theinvention anticipates a more reasonable UL standard than new UL LEDlight standard 1786.

Finally, as shown in FIG. 15A to 15C, the light source (S76) isconnected with the connect-means (S75) and may be a single LED, singleEL element, or a printed circuit board (PCB) with a plurality of LED(s),as long as the sealed-unit output end has a low voltage electric signaloutput which cause no harm to people of any age. Hence, the light source(S5) (S76) (S12′) and its related electric components have no need to beinside an anti-flammable housing or enclosure as required by the currentUL LED light device standard and the common light source(s) can beinstalled inside the light device rather than inside the AC poweredsealed-unit or DC powered battery-pack to save a lot of cost.

FIG. 1 shows a first preferred embodiment of an AC powered sealed-unit(1 a) having openings (1 a′) (1 a″) (1 a′″) to allow an inner lightsource (not shown) to emit light from the top and sides of thesealed-unit to a viewer. The sealed unit has power source means (1 b) tosupply power to the inner circuit means (not shown) and the circuitmeans will be activated by the trigger means (1 c) to cause the lightsource to turn on and off according to predetermined light functions,brightness, color, duration etc. The sealed-unit has assembly-means (1d) (1 d′) (1 s) (1 q) to assemble the sealed-unit to a main housing by atwist-catch or screw-fastening method, or any conventionally availableskill for assembly.

The one extended conductive means (1 h) passes through the hole (1 g) toconnect with quick connector female end (1 i) which can connect withquick connector male end (1 p). The quick connector can be replaced byany connector available from the marketplace, such as a pin, wire clip,solder, copper connectors, catch, etc., which are wide used oncomputers, consumer electric items, and communication items. The maleend of the quick connector (1 p) is connected with remote light sourceor light source set (1K) having a plurality of low power consumptionlight source(s) such as multiple LEDs, preferably on a circuit board(PCB) or flexible printed circuit board (FPC). Up until today, UL hasrequired the light sources (1K) (1P) (1 i) (1 h) to be sealed inside theenclosure or housing, but the current inventor thinks that these lightsources (1 k) (1 p) (1 i) (1 h) do not need to be sealed within anenclosure because they require only a low voltage and current. Theinventor is the first to challenge the UL regulation and believes thesafety regulation will change to accommodate the current inventiondesign. The components (1K) and (1P) can be commonly used by the ACpowered sealed-unit or DC powered battery-pack, which is a veryimportant feature of this embodiment of the current invention. Theconnector-means (1 p) and (1 i) can be any kind of connector-means suchas a quick connector with two conductive-means to deliver electricsignals from the sealed-unit to the remote light source.

FIG. 2 shows a second preferred embodiment of an AC powered sealed-unit(2) which has the same construction as that of FIG. 1 but includes aplurality of openings, windows, r cut-outs with different geometricshapes. This exploded view shows all parts on each location of thecylindrical housing members (2 a) (20 (2 r), including prong means (2 b)(2 v), circuit means (2 c), a plurality of light means (2 d) (2 d′),trigger means (not shown), a top lens (2 e), cylinder lens (2 r),assembly means (2 g), extended conductive wire (2 t), connector means (2h) (2 k), and remote light set (2 n) to provide the AC power sealed-unitwith the best light performance. The top lens (2 e) allows the innerlight source to be seen on front of the prong. The cylinder lens (2 r)prevents people from touching inner electric components inside openings(2Z), windows (2 w), and cut-outs (2 u), and can be translucent sincethe sealed-unit only needs front illumination. It also can be atransparent material for side illumination with pre-designed printing,masking, stenciling, and/or painting with art work so allow the lightbeams to spread out to all sides with special light effects such as theelectric light wall paper shown in FIGS. 7, 8, 9, and 10. In aconstruction such as the one illustrated in FIG. 7, the centersealed-unit with a slot-shaped opening (7 a) and outer cylinder lens hasother slot openings (7 b), and at least one of the slots can changeposition to change the gap width from narrow to wide and cause the lightbeam to be emitted out of different gaps to obtain the bright and darkstripe effect shown in FIGS. 9 and 10. This will result in a light imagegap with changeable features. This kind of changeable image gap offers avariety of images for the electric wall paper, and will let peoplechange the electric wall paper according to their moods or temper fromtime to time. The light device also can be changed back and forth froman AC power sealed-unit to a DC powered battery-pack to enable use indifferent locations such as a bedroom, bathroom, mobile home, RV, orcamper to offer a very practical and useful low power consumption lightdevice with image changeable dark and bright gaps. The up-grade modelfor electric wall paper not offers black and white images with differentgap widths, but also can be designed with some art work on the outergeometric lens by painting, stencil, masking, a printing process, etc.,to create an image such as the shown in FIG. 8 to provide nice andpretty electric wall paper effects. The light device (8 a) is placed ona wall with the art designs on the outer geometric lens (8 b) to projectan electric wall paper with art-design (8 c). This will save people alot of money for regular painted wall paper. Furthermore, the currentinvention of electric wall paper effects also can apply to a lot ofnicely shaped LED night lights, such as the ones shown in FIGS. 11 to15, each of the LED night lights (11 a) (12 a) (13 a) (14 a) having anAC powered sealed-unit on its base and having a rotatable outergeometric lens (11 b) (12 b) (13 d) (14 c) (15 a) (15 b) (15 c) with anart design. Not only can the AC powered sealed-unit create electric wallpaper with pretty light effects, but also the top cover has openings (11e) (11 f) (11 g), windows (12 d), and cut-outs (15 d) (15 e) (15 f) (15g) to make light effects such as (13 e) (14 e) for top areas too. Thisis not an electric wall paper but will still offer very nice accentlight effects to viewers.

In summary, FIGS. 1, 2, 7, 8, 9, 10, 11, 12, 13, 14, and 15 show lightdevices with the following features:

(1) Interchangeable power sources including an AC power sourcesealed-unit and a DC powered source battery-pack that can beinterchanged at any time.

(2) A light source that can be installed within the light device andcommonly used by the sealed-unit and battery-pack.

(3) An AC powered sealed-unit in a geometric shape with outer lens tocreate electric wall paper effects for geometric art projection to awall or desired surface.

(4) An AC power source sealed-unit or light device housing-member havinga plurality of openings, windows, or cut-outs to allow the inner lightsource(s) light to be emitted out to a viewer for a desired lightperformance and light effects.

(5) An AC power source sealed-unit with remote light source which doesnot need to be put into an enclosure to meet safety test laboratorystandards, with electric signals instead being delivered from thesealed-unit to the remote light source by conventional connect-means.

As shown in FIG. 3, a preferred AC power source sealed-unit (3 a) has aplurality of opening (3 c), windows (3 h) (3 h′) with assembly means (3d) (3 d′) (30 (3 f′) such as a twist-catch or screw-fastener forassembling the sealed unit to the light device. The sealed-unit hasprong means (3 b), circuit means (not shown), a plurality of lightsources for different directions (corresponding to those disclosed inthe inventor's U.S. Pat. No. 7,455,444), and trigger means (not shown).The opening (3 c) allows light beams to be emitted through the frontlight device housing member. The plurality of windows (3 h) (3 h′) maybe in any geometric shape and size to allow the different orientationlight source(s) to emit light in a variety directions to provide a lightperformance with predetermined light effects, color, illumination,brightness, dark areas, and/or art-design on a desired surface or area.The twist-catch (3 d) (3 d′) can fit into all kinds of the lightdevice's uniform housing compartment-means to fasten a sealed-unittightly to the light device. The twist-catch (3 d) (3 d′) canalternatively be replaced by any kind of assembly means such as ascrew-fastener to perfectly assemble the AC power sealed-unit with thelight device housing-member.

FIG. 4 shows a fourth preferred embodiment in the form of a light device(4) having a cover (4 b) that can be rotated 360 degrees to cause theinner light source to emit light in any desired orientation at any time.The light device (4) is assembled with an AC powered sealed-unit (4 a)by a twist-catch and the sealed-unit has its own power source (4 c) (4c′), circuit means (not shown), and/or trigger means (always on ormotion sensor), and uses a light source which is built into the saidlight device's (4) housing-member and connected with the sealed-unit.Hence, the sealed-unit (4 a) does not need its own light source withinthe sealed-unit. This will enable the light device (4) to have the samelight performance when replacing the AC power sealed-unit with a DCpower battery-pack because the light source is always installed insidethe light device's housing-member. This is different it's thearrangement disclosed in the inventor's prior applications which havetheir own light source(s) within each sealed-unit and battery-pack. Asshown in FIG. 4, the light device is similar to a marketplace rotatingnight light.

A battery-pack provides a DC power source (58C)with a cover (58 d) to fit into a uniform compartment-means (58 e). Thebattery-pack (58 c) and its circuit and trigger means can be replaced byan AC power sealed-unit to make this kids' flash light into an ACpowered flash light when connected with an outlet by prong means or plugmeans remote from the sealed unit.

FIGS. 7, 8, 9, 10, 11, 12, 13, and 14 may utilize the constructiondiscussed above in connection with FIG. 2.

FIGS. 9 and 10 show preferred embodiments of a LED light device (9 a)having prong means, circuit means, and an LED or LEDs arranged insidethe main housing, which has a transparent cover to transmit light beamsfrom the inner LED/LEDs.

The LED/LEDs shown in FIGS. 9 and 10 can be arranged to emit lightinwardly or outwardly so as to be visible over angles ranging from 30degree to 360 degree. For example, to get 360 degree illumination on awall, one may use three LEDs each having a 120 degree of light emittingangle and arrange the three LEDs on the edge of the maximum distance tothe center of circuit board, so that each 120 degree LED's light beam isemitted through the center to the opposite edge and providesillumination over the resulting 120 degree arc. If one puts the 120degree viewing angle LED on the edge and emit light outwardly, however,the LED will not cover a 120 degree angle of the front cover, shade,screen, opening, cut-outs, grill, or holes because the distance from theLED to the front cover, shade, screen, opening, cut-outs, grill, holesis too close so the function of the front cover, shade, screen, opening,cut-outs, grill, or holes is useless and the special geometric art'slight patterns cannot be created. In order to get 360 degree electricWall-Paper light performance, at least three LEDs need to be installedon the edge of the circuit-board and each LED must face inwardly toprovide enough distance from the LEDs to the front cover, shade, screen,opening, cut-outs, grill, or holes so as to use the front cover, shade,screen, opening, cut-outs, grill, or holes to provide a good light blockand through passage to project the geometric art on the wall. FIGS. 9and 10 show the special light performance for the current invention. Itis important to prevent people from touching the electric components soa transparent cover is needed to cover all said LED or LEDs inside.Other units without this transparent cover are not safe at all.

Some geometric art light performances may not require the front cover,shade, screen, opening, cut-outs, grill, or holes because the LED itselfhas it's a shape which can create a “V” shape super bright light patternon four sides.

In order to get a 360 degree geometric art light performance with all ofthe LEDs arranged emit light inwardly, so the LEDs' height must be thehighest of all other electric components so that the light beams canbeen seen.

The main-housing can be connected with the front cover, shade, screen,opening, cut-outs, grill, or holes by conventional assembly means asillustrated in FIG. 3 (3 d) (3 d′), FIG. 4 (twist catch), FIG. 5 (fixingmeans), or FIG. 6 (screw). All these assembly means are available fromthe conventional market and skill to attach the main-housing to anotherfront body, which is optionally used to provide a desired geometric artlight performance as discussed above.

The front body shown in FIG. 9 may be made up of several pieces such asan opaque lens (9 d), grill (9 b) (9 b′) (9 b″), or opening (9 c) (9 c′)(9 c″). The light will be blocked by the grills (9 b) (9 b′) (9 b″) andpass through openings (9 c) (9 c′) (9 c″). Any kind of arrangement toblock the light beams and let light beams pass therethrough will stillfall within the scope of the current invention skill including anydesired combination of grill, openings, cut-outs, stencil, film,electric components' screen, slide, textile, fabric material, plasticpiece, metal piece, wooden piece, paper piece, and holes. This is veryunique to the current invention and is possible because the main-housingunit for the interchangeable power source universal unit has its ownlaboratory test report with its own safety certification so that anyfront body can be added to the universal unit of the current invention.Even a tissue paper front body on the universal unit would still fallwithin the safety regulation.

Hence, the special light performance LED light device of the currentinvention is very good because it can create an electric wall paper orother geometric art performance in a very simple manner, so that LEDlighting is no longer just for illumination but also has its decorativevalue too.

Examples of a suitable “sealed-unit,” in which all electric componentsof the light device may be fitted, are disclosed in the inventor'sabove-cited U.S. patent application Ser. Nos. 12/527,631; 11/498,881;11/255,981; and 11/094,215.

The “sealed-unit” has its own power, LED, circuit-means, and attachmentmeans so that it can fit into any LED light housing as long as thehousing has a uniform compartment. The “AC powered sealed unit” can usea 110 Volt 60 Hz or other high voltage connection arranged to meet allsafety standards without any hazard of short circuits or potentialdamage during laboratory tests and procedures related to safetycertification.

The uniform compartment of the LED light housing has a construction anddimensions that enable the “sealed-unit” to easily fit into thecompartment. The current invention further includes a “DC battery-pack”which has its own outside dimensions similar to those of the “sealedunit” to also fit into the “uniform compartment.” The “DC poweredbattery-pack” can replace the “AC powered sealed-unit” at any timebecause both have their own power, LED (optionally), circuit-means, andattachment means to fit into the same LED light housing as long as thehousing has a uniform compartment.

The current invention provides an LED light that can change its powersource from AC to DC or DC to AC. This is a further improvement of the“AC power sealed-unit” described in the co-pending patent applicationslisted above, which saves a lot of tooling for different shaped LEDlights and also saves a lot of laboratory testing expense and time.Furthermore, the interchangeable power source also can save a lot oftooling costs, time, and labor to provide a good LED light having apinhole-imaging function (or functions of other LED lighting fixtures,laser LED light devices, etc.) with a same nice shape but with differentpower sources to enable the light to be used in different locationswhere people stay. This is one of the advantageous features of thecurrent invention. Not only does the invention apply to all differentshapes of LED night light, but also enables a traditional puck lightpowered by a DC battery to also be powered by AC so long as people payfor extra parts to hang the traditional puck light on an AC outlet.

While the above-discussed preferred embodiments show the scope of thecurrent invention, it is to be appreciated that any alternative orequivalent design, construction, modification, up-grade, and so forthwill still fall within the scope of the invention, which is not limitedto the above discussed or mentioned details. Any alternative orequivalent arrangement, process, installation or the like may still fallwithin the scope of the current invention, including variations in thepower source, conductive means, geometric shape of LED-units,connector-means, circuit means, sensor means, switch means, LEDelements, attachment means, fixing-means, tightening means, and/orresilient conductive means.
